I have created a small script which simulates having a FLIR scope on sniper rifles. The FLIR is only available when the player is looking through the scope of the rifle. FLIR can be enabled and disabled. Also, the mode can be changed between white and black.
Instructions included in the Readme in the download on getting the script to work in your mission.
Enjoy!

This script has been tested. Its 100% ready to go.
